German luxury auto maker Audi has recalled around 5,000 cars in Europe. The reason behind this recall is to fix issues with the emission control software which emitted nitrogen oxide beyond the permissible limit. According to the manufacturer, it will update the software in 4,997 units of the A8 which are powered by the 2.4 litre V8 diesel engines.

According to the reports, around 3,660 of the affected cars are in Germany and were manufactured between the time period since September 2013 to August 2017. However, Audi will begin updating the software in a phased manner, starting from the first quarter of 2018. While Audi will ensure that the new upgrade does not affect the fuel consumption or performance, it will also make sure that with this update, during cold engine starts, it will be capable of quickly reaching optimal operating conditions for the exhaust-gas treatment system so that its emissions are improved in real driving conditions.

Apart from this, Audi’s parent company Volkswagen has been in news due to the dieselgate scam in 2015 as it was found to have illegally manipulated the engine software to meet nitrogen oxide (NOx) emissions standards in laboratory testing but not in real-world conditions. Although the dieselgate scandal had been put to rest in the US, the luxury car manufacturer has reported the matter to Germany's road transport authority KBA, which was concerned about the possible illegal manipulation of emission levels.

Also, considering the real world conditions, it has been found that Volkswagen vehicles could emit up to 40 times over the permissible limits. However, the company had also witnessed a sharp 20 percent drop in shares when the scandal was revealed.
